Cause if Mrs. Barrett is written as being a ditz, Phillip's right behind her.
So we have three main characters for this episode. Mr. And Mrs. Barrett. Mrs. Barrett might be married but she has her attention on Phillip and the feelings are mutal from Phillip's point of view.
Phillip's got a plan to get Mr. Barrett out of the picture. I do think he's got more brains than Mrs. Barrett but he's truly not far behind her. He writes Mrs. Barrett a letter and definitely implicates himself in what will turn out to be Mr. Barrett's murder. He lists a couple of instructions for Mrs. Barrett to follow while all this is going on. He wants Mrs. B to write Mr. B a swarmy letter. This is all very hard on Mrs. B because she doesn't know what swarmy means. She also thought Canada was overseas at the beginning of the episode. The second thing Mrs. B is supposed to do is throw a little get together. Mrs. B finally gets her swarmy letter written and she folds all the pages together (including the letter Phillip sent her!!) and off she goes to the mail box with it.
She gets back and it doesn't take her long to notice she screwed up. Where's Phillip's letter? She realizes it must be in the letter she sent her husband. She has to get her letter back! Her maid's getting canopies made for Mrs. B's get together while Mrs. B makes a mad dash around trying to get her letter back.
She ends up at the post office and she's told that mail's already out. She goes back home and tries to call her husband. She has all the hope that Phillip's plan failed. Nope, her husband isn't there. Needless to say, Mrs. B's got too much on her mind to be into her get together. Is a ray of hope for Mrs. B about to arrive? A man that works at the hotel says Mrs. B's letter came back. Mrs. B didn't put enough postage on the envelope. Mrs. B's hopes are crushed as she's told that he put more postage on the envelope and sent it back off.
I just adore this episode. It's an interesting storyline but I really want to give bonus points to Sarah Marshall (Mrs. Barrett). I loved the airy, ditzy voice she used for the character.
